Ranpak claims FillPak is the fastest most economical voidfill system available. Three operating speeds are standard: 20’’ per sec 35’’/sec and 55’’/sec. The system is designed to fit over any conveyor to dispense product directly into a box. FillPak converters create a star-shaped tube of paper which is geometrically the most efficient way to fill void in the top of a box. One box of fanfold paper can be connected to another to reduce downtime; this arrangement eliminates changeover time enabling all of a packer’s labor to be directed toward filling boxes.
